hi all I just had a look on the Benq scanner cd in ther drivers directory and there are 9 *.bin files in that directory: u34v110.bin u96v121.bin u174v041.BIN u176v046.bin u222v067.bin U64V120.bin U126V043.BIN U190V044.BIN U192V074.bin Does anyone know which is the right one? also, on a completely different subject, does anyone know about the 'STACKS=' entry in the config.sys file of win98? Everytime win 98 loads, it comes up with the error, 'An internal stack overflow has caused this session to be halted. Check the stacks setting in your config.sys file, and then try again'. I have consulted Microsoft's website Knowledge base over the problem, and I have the STACKS=64,512 and yet it still comes up with that error. Does anyone have any experience with this error? glenn
