PT 7.4 buggy graphics with track/group colors. Culprit?

[Mt.Everest]

Hello,

I've been making more use of the track coloring options lately- Having the whole channel strip in the mix and edit window reflect the color of a group or say, making all my FX returns green, etc.

However, it is EXTREMELY buggy. Sometimes the tracks lose their color, sometimes simply scrolling halfway up the screen where 2 of 4 tracks get hidden, then when I scroll back down, those 2 tracks have lost their color.

Also when I remove a send or plugin, the little rectangle where the send WAS stays gray, while the rest remains colored. The list goes on and on.

Im running a PowerPC Dual 2.3, Tiger 10.4.11, and PT HD 7.4cs10.

I used to use 3rd party apps like Labels X and Window Shade X. But I turned those off and the problem remains.

Has anyone experienced this? Any tips on what could be causing the colors to go away, come back, and everything in between?

Its really frustrating that I get everything color organized only to end up looking MORE disorganized than not using any coloring at all since some tracks or groups within a color set lose their color randomly. And I see no pattern in the behavior.

Thanks in advance for any advice!
