I had to change the video resolutions for full screen and windowed mode to match my desktop resolution and color depth (16-bit). Then set the file (EQCLIENT.INI) properties to "READ-ONLY" so it cannot be changed back to anything else. Now I can move my mouse around all I want during login and EQ doesn't crash.

[VideoMode]
Width=1024
Height=768
WidthWindowed=1024
HeightWindowed=768
WindowedWidth=1024
WindowedHeight=768
FullscreenBitsPerPixel=16
FullscreenRefreshRate=60

This has been working flawlessly for a week now so I thought that it was time to update my post. Keep in mind that while the file is locked in Read-Only mode you can still change settings in the game like resolution/color/text/etc. like normal, but you will loose it th next time you run the game. If you want or need to change anything, just undo the read-only attribute, run the game, change what you want, exit the game, *DOUBLE CHECK THE VIDEO SETTINGS* (especially the refresh rate as it tends to get set to zero.) and then set it for read-only again.
I hope this helps others out there.
