OpenGL performance is sluggish when multiple sequences open

I may have reported this before, but now I can easily reproduce it. Here are the symptoms:

Sequence Editor v2.9.4.

Usable when a single sequence is open. When multiple sequences are open in tabbed mode (default), any drawing operation takes an extremely long time, while the sequence editor is using 100% CPU. (Actually 50% on this dual core.)

While it is drawing, the drawing appears in areas of the screen that it shouldn't, for example it will draw on the window that is on top, or to the left of the sequence editor window.

I tried turning the hardware acceleration off, but then the sequence editor crashes after using it for a couple of minutes.

My system is nearly 6 years old, so maybe it's time for a new one. Anyway here it is:

Dell Dimension DIM9100
Pentium 4 CPU 3.00 GHz 1.00 GB RAM
Windows XP Pro SP3
RADEON X300 SE 128MB HyperMemory
The ATI driver is 6.14.10.6525, dated 3/29/2005.
