[MACTCL] reinstalling after crashes...

[Andrew W. <an...@aa...>]

Hi,

while testing some tcl/tk applications I sometimes run into a bug
that is big enough to crash MacOS 9x - typically the window manager
locks up, clicking on icons doesn't work, that sort of thing.
Force Quit isn't enough to free up the system so eventually I have
to reset the machine.

Sometimes, after such a reset, an existing application built by
the 'Drag & Drop Tclets' app will stop working.  eg, when running
8.3.3 I'll sometimes see a dialog box saying that the application
couldn't be run because tcl8.3 couldn't be found.  I check the file
system and all the folders and libraries are in the usual place,
nothing obviously missing.

I've found that uninstalling the 8.3.3 distribution and then
re-installing it solves the problem.  After re-installing, the
existing application built by the 'Drag & Drop Tclets' app will
work again.  So, ok, sometimes re-installing helps.

About uninstalling...  I'm new to Macintosh so I didn't know about
the implicit Restart required when uninstalling software.  The VISE
uninstaller doesn't actually delete files, instead it moves them
into invisible folders and signals the OS that it should *really*
delete the folder the next time the machine boots up.  The VISE
uninstaller doesn't say "you must restart to make these changes
take effect", but it would be helpful if it did.  I found that
nievely uninstalling and then immediately installing tcl8.3.3 (no
reset) wasn't enough to fix the "tcl8.3 couldn't be found" error-dialog
problem.

I hope this helps someone ;)

Cheers,
Ay.
