[8525, TyTN, MDA Vario II, JasJam ROM Development] CRCinAU:
I'm not sure what to say here... I just opened up File Explorer, went to \Windows and used the scroll wheel to scroll through the entire \Windows directory with no issues at all.

Is it possible that a 3rd party program is causing this issue? Have you tried running the ROM by itself and not installing any software? Does the problem still happen then?

EDIT: If people having issues can also run a bare R10 install for a week and see if the lockup/hang/reset issues keep happening, it would be very useful. As well, if you can list the programs you have installed - and the order in which you install them. I have a feeling that the issue is being caused by a 3rd party application/software/patch. I've been running R10 on my device since the 10th and haven't been able to duplicate any of the issues people are reporting.

EDIT2: I would also like people who are having issues to check their device for bad blocks - as some of the issues being described seem to be very similar to bad block issues... To do this, you need to have loaded HardSPL onto your device (and if you haven't already got it, why the hell not!?!). You'll need a copy of MTTY.exe and this thread. If you have any bad blocks, fix them, reflash with Release 10, and see if it fixes all your issues.

If you don't have any bad blocks, it should look something like this:

If you see something like this:

Then you will need to run 'task 2a' and wait for it to complete. When completed, reflash via SD Card and see if your problems are resolved.
