Thanks for link, but no applicable. Error only comes up when I try to open an email and none of the items in the ms article apply.

I have been running 4.41 for a long time and apart from pmails usual problems it has been ok. Of late I have been getting windows splash errors titled winpm-32 with text "out of rresources". I press the OK but another pops up and only way of getting out of the loop is to use task manager to kill the main winpm-32. I have tried searching the forum but can find nothing on this subject. Anybody any ideas?

I suppose it has nothing to do with Pegasus Mail; take a look at: http://support.microsoft.com/kb/142719
