I use code compare a lot, because it works great with approval tests.
This is probably a different use case than you are expecting. I means I will open a diff tool maybe once every 2 minutes, or 240 times a day. as a result I have detected a memory leak you might not be aware of. None of these files are very big ( < 30 lines) and once the memory is full, it doesn't matter the size of the file, you have to restart VS to get it to work again.
would love if this was fixed.
thanks.
