[Laszlo-user] Bug in basefocusview

[J Crowley]

Hey, Dmitry.

Thanks for finding this and bringing it to our attention.  The best  
way to log this and get it assigned and prioritized, and to keep it  
on our radar, would be to file a bug in our JIRA bug database, which  
can be found at http://jira.openlaszlo.org.

We appreciate your contribution,
J Crowley
