I have created several EXCEL files with extensive VBA code and ActiveX controls from the Controls toolbox. I have installed them all on several office computers and all were working very well. I recently created another file which worked fine until the last change I made. Now it will not load at all (Not Responding - on Win XP and Application Error, Close or Ignore on Win 98). In addition, as soon as I loaded this new program on the office PCs, they will not only not run this program but will not run any of the other xls files that used to work fine. The common demominator appears to be ActiveX controls. If I take an archived file and replace ActiveX buttons with Forms controls, the programs go back to operating just fine. The problem is, I need to get to the files on the office computers as they have embedded client data on them. Any way to reset the way Excel treats ActiveX files? I desparately need to fix the problem with the office computers. Any help would be appreciated.
