Why does Blender 2.28 seem so much slower. The 3D editor and button windows respond at a slower rate. I made a little particle system and I could watch each one being updated as I changed frames... 2.27 and earlier had no such problem. Any advice?

My computer:
1.6GHz P4
256MB Ram
GeForce2 64MB
Windows XP

I withdraw my question. It seems slow fonts are the culprit. If I could help code blender I'd arrest it (the... culprit... get it... goes back to Blender which is working much better now)
