Most likely.

SHSUCDX's local stack has a size of 180h bytes. AFAIU it tries to use 0C0h bytes from its PSP, so if it is loaded without /C, the true stack size is just 180h - 0C0h = 0C0h. That's still sufficient for most cases, but if a mouse is used and the current application has installed a mouse event proc, it might be too small. The game KYRANDIA 3: "Malcolm's Revenge" is such a case (it's one of my favorite test cases for Jemm).

[edit]
even if SHSUCDX is loaded with /C there is still sometimes a problem - an indication that a local stack of 180h bytes is too small. What then helps is:

1. don't set STACKS=0,0 in config.sys
2. use Jack's SHCDX33C. This has a local stack of > 200h bytes.
