PMC Files disappearing in Windows 10

[aircooled]

I've been working with PMC 5.0.5 (x64) several months in Windows 7 without any kind of problem.

I have now a brand new laptop with Windows 10 and files are suddenly gone at (apparently) random times without any kind of reason.

I was working with 4 pmc scripts which I opened with PMC's very own 'recent files' menu. Suddenly one of the files (while I tried to open it) responded 'this file does not exist'.
I never recoverd that file, tried with Recuva and other programs the file was GONE. Luckily I had a backup but still I missed several hours of work.

So I moved everything to Dropbox. Yesterday a new incident: 'the file does not exist'. WTF!!?? I went to Dropbox: 'file deleted 3 minutes ago'. I NEVER deleted the file.

I have Googled and apparently it is a known Windows 10 bug that appeared 2014 but MS has done nothing.

I feel safer with Dropbox but still, very enerving when it happens. Anyone else has this experience?

It is ONLY PMC files that disappear.

When it crash during PMC tries to save the file, the file got deleted.
