Hi all,
I've been trying to track down a recently discovered bug in
one of my Blackbox programs. So far, it appears to be a bug
introduced into the Blackbox framework at v1.5. When I
minimize ne of my windows in a particular application, I get
a trap.
In my search for where this bug came from, I took source
code that I was using in version 1.4, and verified that it
worked fine. Then I installed a pristine version of 1.5,
copied over the source files, recompiled, and ran this.
It crashed.
Now, this certainly could be something about my View Restore
procedures that happened to work in 1.4 but not 1.5. Although
I'm not sure why the framework should be calling my View restore
procedures when the window is minimized?
Anyone familiar with this?
Marc
P.S. Here is an example of the trap I get when I minimize
one of my view windows (my module is called "StatDisplay")
