I received some very valuable information from an expert member who really gave me insight into what might have happened. I goofed up by answering him personally instead of in the post so his valuable information is lost to everyone but me, unless he would like to post it himself.
Here is what I learned from him:
1. I'm grateful to know that the Windows Registry does not rule Pegasus. That's a huge relief so I don't have to dig through it for lines to correct and I don't need to worry about one standalone program confusing Windows by the installation of another.
2. I may know now what happened to cause my problems in the first place, now. My computer was "crashing" right before the Pegasus copy folders got all mixed up and my Pegasus nightmare began.
As I have now been taught, Hierarch.pm loads the order of the folders into memory, which I will assume the Cache.pm file is all about. If the computer or Pegasus happen to shut down before this process has been completed, it can corrupt the Cache.pm file since the information in Hierarch.pm has not fully loaded.
I keep my computer on all the time, especially so my virus patterns can update. And my Pegasus program is open all the time since most of what I do relates to using email. I keep my system on full power, with no power-downs, no hibernation, no energy savers... always just flat-out running at maximum. This may cost more, but I don't like anything taking over my system unless I command it thus.
I do have an APC UPS system on at all times, especially as I live in Florida, the "lightning capitol of the USA." So, I figured that I was pretty safe from potential for corrupting files.
But, suddenly I was getting "insufficient resources" messages and the computer was either freezing up or shutting down.. Of course, Pegasus was usually always open. So, it was not being shut down properly and sometimes it was not allowed to load fully before the system froze and I actually had to power off since there was no other way to recover.
Now that I have been taught by a kind and generous expert member, I can easily see why my Hierarch.pm and my Cache.pm files may have contained inconsistent information. Once the files were corrupted, I was not able to track down the problem and correct it.
At first I thought I had a bad memory chip or that I was running low on hard drive space. But nothing I did helped. As it turned out there were some drivers on my computer which needed updating and once I updated, and removed some large graphic files, and adjusted virtual memory for the umteeth time, the resource insufficiency went away...but I was still stuck with the copy folders mess in Pegasus.
Now I have cleaned out what seems to be the damaged folder and I'm hoping things will work the way they are supposed to.
Another thing I noticed, and I have no idea how this happened, but an email I sent from my Android phone and opened in Pegasus, as I normally do, somehow went from about 350 k to 5.2 megs... No idea how that happened but surely it was a corrupted file. I weeded it out with two others which somehow grew.. and I"m hoping now that I've had a good shot of Penicillin to fix all that has ailed my machine.
It still remains to be seen whether or not I've got this all fixed, but I may need to download a fresh program and reinstall to overwrite any program files which might have been corrupted in the interim.
This has been a tremendously valuable learning experience for me and I sure hope that the generosity of the expert members who have been so kind to me will go on giving for a long time as others read this thread and find their way out of a similar mess.
I will report back when I have had my "shakedown cruise" and am sure this boat will now stay afloat.
Thanks again sooooo much.
