Photoshop CS4 crashes when entering value in panels
Hi,
I'm using Photoshop CS4 on my Macbook Pro 2009 with OS El Capitan 10.11.6. The program crashes when entering (or trying to enter) a value in the panel of an adjustment layer. This happens about 75% of the time I do this and I sometimes I can't reopen the program and can't even force quit it—like it crashes but doesn't fully quit. I'm also not able to reopen it or even restart my Macpook Pro, like some parts of Photoshop (in the memory or something) are blocking the computer to restart. I have to shut it down using the power buttton to cut all ties with Photoshop.
Do you know what could be causing the program to crash?
Thanks!
-Ben.
