I don't know if it does or not, but that's the first thing that came to mind when I saw the illegal operation message. It seems weird to me in any event that the CAB file, which included "palmsizepc" in the name, would fail to install the proper runtime files, without the user being informed of required additional files.
(Guess I should get used to this, though.
)
(BTW, I did have to reinstall mfcce211.dll in the E-105 because of problems with my Belkin NIC identical to those I had had on my MP790. Haven't had time yet to investigate hexeditors for either platform. I do have CEProbe on the E-105, which does show what appears to be a long list of hexadecimal values associated with each application, and the value entries appear to be editable. But I don't assume that this means that I can use CEProbe as a hexeditor. Also, while CEProbe is freeware, it says it's specifically for the Palm-size PC platform, and I tried installing it on a couple of my H/PCs some time ago and it wouldn't work.
