Tcl goes into an infinite loop when used with attached Tix
file. To recreate the inifinite loop click on the scrollbar
and drag it down to the last item.
It can be recreated with the following setup
Windows NT, Windows 2000
Tcl - 8.4.2
Tk - 8.4.2
Tix - 8.1.1, 8.2.0
This seems to be a corner case, since any change in the
number items to be displayed on the tixTree or window
height or pady or TIX_DEFAULT_SCHEME in tixInit.c does
not recreate the bug.
To recreate the bug in other versions of Tix e.g. 8.1.2, 8.
1.3 etc, change the following line in tixInit.c
#define TIX_DEF_SCHEME "WmDefault"
#define TIX_DEF_SCHEME "TixGray"
A preliminary debug found by attaching the VC 6.0
debugger to the errant program showed the stack trace
