I don't know if you guys use 4K displays for your dev work, I sure do, but anyways...
...using VS2008 on a 4K display was driving me crazy!
Every time I attached to the target to downloaded an image the VS window and dialogs shrunk to a size where the text was readable but extremely small and very painful [for me] to read.
Here is the fix, jic you've encountered this as well.
Regards,
Doug
