I finally found a solution for a bug that has been haunting mySolidworks experience ever since version 2007: File menu delay.

If you are experiencing a lengthy delay or temporary lock-upwhenever you attempt to pull down the "File" menu, here's thesolution: Disable Write Combining.

Here's how:
Put your mouse on your windows Desktop. Right click and selectProperties.
Next, on theSettings tab, click onAdvanced.
In theTroubleshooting tab you'll find a checkbox near the bottom,"Enable write combining". Uncheck that.
Reboot.

(This feature is there purely for backwards compatibility forhardware that would certainly never be used for a modern PC runningSolidworks.)

Also, this solves the problem of an occasional delay and lock-upwhen using CtrlTab in SW2008 to toggle between open Solidworksdocuments.

Hope that helps!
