Command Line Plugin Crashing Explorer - Random crashes with plugin

Windows XP SP2, IE 6 SP1
TrueLaunch Bar 2.2.0.7 Beta
Plugins in use: Spacer 2.0/Command Line 1.0

Apps running in memory:
RemotelyAnywhere
Symantec AntiVirus CE 8.0
TimeCalendar 1.6.6

Haven't touched anything for a week except adding the Command Line plugin. Now randomly have various Explorer.exe crashes, at least twice a day. Remove the plugin and everything seems to be okay again. Don't know for sure, but it seems to happen shortly after I use WINDOWS+E key combo to use the built-in Start > Run command. For example, I might use WIN+E, then type in a path, start browsing the subfolder structure, then explorer crashes. Can't verify that it has happened in each instance. I do know that it only happens with the plugin enabled.

Thanks.

Found the following in the Event Logs. Same DLL each time.

Faulting application explorer.exe, version 6.0.2800.1106, faulting module ntdll.dll, version 5.1.2600.1217, fault address 0x000085c0.

Hope that helps...
