I did mention comctl32 several posts back. I ran the dependency walker. Sheesh. My computer background is mainframe computers and operating systems. I understand PCs, build my own but have only written a hand full of programs for the PC mostly in C. (I coded in COBOL, FORTRAN IV and IBM 370/Assembler and VS/Basic mostly, yes I'm a dinosaur

). I know the theory behind DLLs but am getting to the end of my troubleshooting ability. I ran the 10Tec_hTooltip_100.dll through the dependency walker and it showed the following errors in its log:
Error: At least one required implicit or forwarded dependency was not found.
Warning: At least one delay-load dependency module was not found.
Warning: At least one module has an unresolved import due to a missing export function in a delay-load dependent module.
I expect that may be significant? I haven't been able to get all the documentation on this dependency walker program to see what all the codes and symbols mean. I will keep looking. If I'm reading this correctly, most of the world as we know it is called by this 10Tec... dll.
