Trying to save from ScummVM's save menu (F5) results in being thrown back to the save menu.
Try this:
1) Press F5
2) Choose a New Save
3) Type in any name
4) Enter
No save game will be created, but you will be back at the save screen.
If you now choose New Save once again and type a name it will save.

Tested on Linux x86_64 with latest development master i.e. ScummVM 1.7.0git6249-g1a18d1a-dirty (Mar 19 2014 21:14:20)
Replicated successfully, thus this is not a Big Endian specific bug.
Looking at the code in engines/tsage/core.cpp and engines/tsage/ringworld2/ringworld2_logic.cpp, I suspect that the issue may be that the F5 event is handled twice, so the save dialog is immediately reopened a second time.
