Well, i find myself posting again with the same old problem. I have an SE/30 running a virgin System 6.0.7 (ran it from my install disks fresh from apple.com) and Microsoft Excel 2.2a (yes, the 'fixed' version). When I attempt to make a selection from any menu other than the Apple I get the bomb box and the message 'heap collided with stack'. When I tried debugging this little mess with TMON, I discovered that Excel uses a mystical new MDEF (ID=5) which seems to have appeared in the system file along with an WDEF (ID=5). MDEF-5 seems to have a nasty 'patch my address back into the MDEF-resource' mechanism to find its vars and for some reason I am getting an odd value which causes a bus error. Since Excel also patches _MenuSelect my guess is that they are stuffing about with it. Badly! Does anyone out there (a) actually use Excel under my circumstances (b) have any idea what MDEF-5 is doing there (my guess is Apple are sticking in support for Microsoft's helpful menus) (c) have any idea how I get out of this mess?

Uh-oh, looks like Microsoft are at it *again* ... :-) > Does anyone out there (a) actually use Excel under my circumstances (b) have > any idea what MDEF-5 is doing there (my guess is Apple are sticking in support > for Microsoft's helpful menus) (c) have any idea how I get out of this mess? (a) I'm using the old 2.2 (*not* 2.2a) on an SE/20 with 6.0.7 with no problems (at least, not yet :-) (b) & (c) Nope, sorry... -- See ya Nigel. /******************************************************************************\ * "If I had a quote, I'd be wearing it." * Internet: stanger@otago.ac.nz * * -- Dylan Thomas (I think) * SnailMail: Information Science, * * * University of Otago, * * "Say no MORE!!!" * P.O.
