If my Alt fsrf does not help, I could tell you a story about what happened to me a few years ago.
Have you noticed any other minor irritations with VB6 IDE ?
I cannot recall how many months this happened over, but my IDE started deteriorating (things not working, etc)
I finally decided that MS's disdain for VB6 (discarded by them like a used condom), meant they were not testing their OS updates, to ensure that they did not impact the VB6 IDE.
I don't recall (I am old) whether I had to re-install the OS ?
I have a vague recollection that my attempts to re-install VB6 were not a piece of cake, so I may have had to reinstall the OS as well.
But what I do recall was, I switched off automatic OS updates, to never darken my doorstep again.
I have never experienced the same problem again.
