I don't know if for you it's the same thing, but since several years i have the same strange behavior :
When i run a code in the PB IDE, the "PureBasic_Compilation0.exe" appears in my folder code beside my PB code (Normal

And when i close it the "PureBasic_Compilation0.exe" disappears (Normal too

But now...it's impossible to rename the folder code

The only one way, is close and reopen PB IDE and after i can rename the folder fo code

Someone have the same behavior or know how ?
Have a good day
