please do ! I suspect HK31 won't install

actually I tested on that one. Won't install the hack.

Of course their source is derived from Microsoft's and partly kept in sync. However quickly peeking at the DOS DATA segment while I was trying to run my hack showed significant differences in the layout. Is PC-DOS 7 supposed to be able to run Windows 9x anyway ? I have not researched whether it maintains a table of loaded TSRs nor whether the MS bug is present. You might be able to help in this respect.

Besides breaking WRAPPER, it broke Geoff Chappell's original CRTDRVR library,for one. Other than those two, I'm not aware of other, commercially or otherwise available, applications that need the patch. The patch is *potentially* needed for any WRAPPER-like driver that is unaware of the "bug".
For instance I hacked MS DEBUG way back (DOS 3.21 times) to be able to launch it as a driver. With my hack, I can now launch TSRs from the modified Debug without crashing the system :-P

Granted, this patch is basically a specialty thing, the main purpose of which will be to use Wrapper in MS-DOS 7.
