I never had any problems with crashing, until recently. I followed Henrik's posts in the past, regarding this issue, but had nothing to add.

Last month it crashed on my work bench laptop. After rebooting the pc it seemed ok and no more crashes. It's a gateway 486 running the last version of XP. This pc is never connected to the net and been stable, running PBP2.6 and 3 for at least 5 years.

A few days ago, I plugged my usb flash drive into the laptop and opened a pbp file in MCS. I compiled the file without problem. Then I saved the file to my MSCX folder. I started to modify a line, and got the error message. After rebooting it would not allow me to modify that file without crashing.

Now days later, I can open the file from the MSCX folder without any crashing.

For me it seems to be a path problem as Forwardbias stated above. Both times that I had problems it was while using a flash drive.

One thing my case indicates is that it has nothing to do with which version of Windows you are running. Same problem on XP, 7 and 10
