Hi, recently after implementing a few TClientDataSet's in one of my modules, my application is now occasionally issuing a "Catastrophic Failure" message when the application quits. A search of the web came up with a several references to problems in the Midas and COM components in both Delphi 4 and 5 that would on occasion generate these CF errors. The two sites that had the most pertinent information are: http://homepages.borland.com/dmiser/midasbug.htm http://www.borland.be/devsupport/delphi/fixes/delphi4/corba.html But I was wondering if anyone else here had come accross these issues/problems before, and if there were any work arounds? I've not tried the VCL patch as mentioned in the first URL.
