That seems spectacularly improbable since the same thing has affected the past four computers I've owned ( two, just with BlitzMax ) and since it happens with no other programs running, even more so since no other programs exhibit the any vaguely similar symptoms.
Of course, as I said, it is much easier to blame the user than the software, even when you have to brush remarkably improbable sets of circumstances off as coincidence.
It's not that improbable. If you have ne shared piece of hardware between all 4 PCs, there could be a screwy driver affecting something. For example something for a router? printer? Or is there some essential bit of software that you choose to run on startup on all of your 4 PCs, which could be interfering?
I realise it seems unlikely, but with absolutely no-one else reporting this, I would say it's more likely to be external software than the IDE. Of course, if anyone else can report this, and we can spot a theme, I'd be more than happy to investigate. AsI'm sure you realise, it is virtually impossible to fix a bug when you cannot reproduce it.
The CE IDE is a tweaked version of the existing IDE, but we are in the process of refactoring a lot of the code, with a view to making some signficant improvements. It was only suggested so that I could find out if your bug affects "my" code too, or if it's just the official IDE, in the vain hope of fixing it.
