Is there a type error in you post are are actually using 4.51 which is quite old and not normally used with Vista or newer systems. Did you actually mean 4.61 version? current would be 4.62 version. http://download-us.pmail.com/w32-462.exe which does include improvements in download speed or checking messages if left on the server.

I have seen other threads reporting that Pegasus Mail sometimes seems to pause & wait, and then go again.

I have tried this version on Windows Vista (x64) and Windows server 2003 R2 (x32) and it seems to suffer the same problem.

Related or not, there seems to be a long delay if I retrieve email via the "File -> Selective mail download" option.The delay occurs after the download has completed, but before the list shows (the status message "[10] or [20 etc] messages downloaded" stays on thye status bar for 20 or more seconds.)

 Any ideas?

 Thanks,
