>Just a SWAG, but you might try altering the screen and keyboard behaviors for the VDM in the PIF, and trying running it in Win95 compatibility mode with explicit memory limits established in the PIF to keep the combined convention plus EMS (FPDOS 2.5 used EMS for it's DOS Extender; FPDOS 2.6 used EMS for it's Standard Edition and preferred DPMI for the Extended edition, and in all cases, the total memory allocated to the VDM should not exceed 16MB or wraparound issues can arise.)

If this is a memory-issue (at all), NEVER use EMS. There will be all sorts of problems occasionally for 100 % sure. This counts for Dos-machines and for W95 machines (the latter usually having it enabled by default).

Note that we didn't encounter such behaviour ever (though we "browse" a lot ;), but pressing left-arrow on the left-most column (at the leftmost char) will give you a C5 (win-machines).
