[Laszlo-user] Mouse tracking - troubles with Local vs Global getMouse

[Benjamin Shine]

Shishir, I commend you on the excellent test case. Hooray for short  
test cases!

I'm not familiar with this particular area of the code,  but I  
believe there have been various bugs around global and local  
positions inside an inputtext.

To help Max track it down -- which browser are you using, and which  
runtime?

To make it an even better test, you could add a writeln or a comment  
about what value is expected versus what value you actually see --  
something like:
Debug.print('Expected 27 for local.green_x, got %d" , local.green_x);

I also invite you to search jira (http://jira.openlaszlo.org) for  
bugs about positioning within inputtext's -- especially look for  
recently-modified bugs.

Finally, please try this in a recent nightly build from trunk.

Thanks for participating in open source distributed quality assurance!
