OK, a tiny bit of context. This has all come about as part of my ongoing quest for my HTPC to behave as I want when it comes out of standby. In short, the PC is going into standby from a batch script that includes a "mc26.exe /close" command, and waking with a batch script that includes a "mc26.exe /library {library name}" command. My MC26 is set up to open in Theatre View by default.
Testing results are slightly odd. All are with windows scaling at 200%, Theatre View at 100%
Full reboot - scaling Ok, as expected, but doesn't use the batch stuff as described above
HTPC only standby/resume - scaling OK, just using the HTPC remote power button
Full AV system standby - Normal situation, AV receiver, projector and htpc all go through standby/wake. Scaling problem occurs
To answer the previous question, with Windows scaling at 100%, the results are the same, with the problem still occuring. In Full AV system standby, Theatre View screens are incorrectly scaled. More specifically, the boxes are smaller, suggesting that they are scaling properly, but the text is still oversized, the same size as in the 200% test, are therefore overlapping the boxes even more.
If I close MC, and reopen it, scaling is ok
