Errors reported when running program using Tk:ProgressBar through ptkdb

swampyankee has asked for the wisdom of the Perl Monks concerning the following question:

When running some code by perl -d:ptkdb program.pl, I get this message:

 error:bad screen distance "" at c:/Perl/site/lib/Tk/Submethods.pm lin
+e 37.

I do not get the same message when running the program directly, i.e., without using ptkdb. This only showed up when I added progress bars to the program.

Any monks with similar experiences?

I'm using ActiveState's Windows Port (5.8.8, binary build 817)

added in an update

When I get a chance -- probably not before the weekend -- I'll provide a program that replicates the error I'm getting.

The value for $Tk::VERSION: '804.027'
The version for ptkdb is 1.1091 (using File => about from the debugger).
The version for Tk::Progressbars is 4.010.

emc

Only two things are infinite, the universe and human stupidity, and I'm not sure about the former.

Apart from some code, please provide your Tk's version number - `Bizarre copy of ARRAY in leave` looks like promising some fun :-) --shmem _($_=" "x(1<<5)."?\n".q·/)Oo.

swampyankee, I use progress bars in a couple of applications, but I have never had cause to try and use the debugger. Do you have a piece of test code we can run? jdtoronto	[reply]

Apologies to all; I've not had time to trim the code down to the minimum showing the problem. It's on my "todo" list. Unfortunately, my todo list is processed only by push and unshift commands. emc Only two things are infinite, the universe and human stupidity, and I'm not sure about the former.
