InstallShield woes

[John Williams]

Thanks to those who have replied.

I have tried Ivan's suggestion of disabling exec-shield.  This makes no
difference.

I have also tried Rick's suggestion of putting the session in a
non-managed window.  This also makes no difference.

Sven's observations did not correspond with mine (re-starting X makes no
difference).

Again, thanks to the people who offered help.  Any other clues?  In
particular, what _exactly_ does the error code 0x80010100 mean in this
context?

Also, is there some way of determining what version of installshield is
used?   I extracted the strings from the binary but there were no clues
there.

Thanks again,

John
