i've been enjoying the vista bricopack for a few days now... however, just recently, this message keeps popping up in the middle of the screen... Run-time error '1400'.... Error getting Thread ID. (&H578): Invalid window handle

what do I do?

thanks so much

The error code 1400 means that Windows could not show status dialog. You can fix it with an application such as Registry Mechanic from PC Tools (it isn't available for free)

Have you tried reinstalling?
