[Gcl-devel] bug #8424 overview: GCL-TK OUR-WRITE BUG

[Camm Maguire]

Greetings!

We believe this issue has now been fixed, in both CVS head and the new branch 
Version_2_6_7pre, shortly to become release 2.6.7.  It would be great if you 
could confirm.

Thanks for your report!

=============================================================================
After successfully mapping a window and filling it with widgets, I preform 
*many* widget calls, each of which specifies a :return argument (i.e., GCL 
waits for Tk to complete the call). However, when too many of these calls are 
made too quickly, I receive the following error:

| Error: Write timeout: ""

This problem shows up on both I386 and PPC.

If you have any ideas how I can fix this, please post or email me. In case it 
matters, this code does not redefine any of its code.
