Alert -> blank WW window -> crashes

I believe this has been reported elsewhere but I can’t find it.

If the alert window pops up and is clicked upon quickly, the WW window opens blank and if I attempt to close it or click on a menu item it then errors out with a Run-time error ‘5’: Invalid procedure call or argument and WW closes.

If I wait a few seconds before clicking on the alert WW opens fine and displays the alert.

There appears to be a timing or sequencing problem with this process.

WW 5.6b3
Win XP SP2


I also get this with WW 5.6 Beta 3
