Running latest Gen 8.5 Interim Release 4.
When open certain models (existing .dat files) with the Gen Workstation Tooslet see message:
The model will be updated to support more than 64K strings, which results a change in the .DAT files. The new files cannot be read by an older release of the Gen 8.5 Toolset, but the model/subset may still be downloaded to an older release of the Gen 8.5 Toolset. Do you want to continue?
