nogrow message to thispatcher causes glitch in jweb?

I've discovered that if you send the message "window flags nogrow, window exec" to thispatcher in the same patch as jweb, it causes jweb to stop working. Is this normal?

I tried this on Windows 7 64 and OSX 10.6.4 and got the same result, so I believe this is a glitch. My apologies if I've missed something about this. I could be mistaken. I've attached the jweb help file with thispatcher to replicate this.

Anyone else encounter this? I've scanned the forums but came up empty-handed--3 hours later, I realized thispatcher was the culprit for jweb's strange behavior.

Best,

V.J.
