I have another newbie problem. I pressed my Caps lock key by accident and and since then AE doesn't want to refresh things like changing layer modes and can't make Ram preview unless the Caps key is pressed all the time. I search to find what it is suppose to do and it appears that it is working in the opposite way for me. AE flashes the red bar with a message to release the Caps key when it is released and I have to press it to refresh.
What could be wrong?
Quit the program, start again. This sometimes happens, when you hit keys all too quickly and the program is engaged in some heavy calculation. Then somehow keys get inverted. Some sort of bug....
