Output window not scrolling

Hi again.

I’ve just installed CS5 on a new laptop using Windows 7. I was running it before on my Windows Vista machine and CS3 on that same machine before that with no problems.

However on this install, the ‘Output’ window isn’t scrolling properly. I commonly use a trace on an enterframe event so I can track exactly what is happening to a variable and when changes occur. The Output window scrolls so it is constantly at the bottom and the most recent trace is visible, except when it gets to about 50 it just gives up and stops scrolling. This obviously isn’t very useful because I can no longer see what the trace is saying unless I scroll down manually (and then it is instantly outdated considering a new trace is produced each frame).

Anyone know why it won’t scroll to the most recent output? It always used to on my other installs.
