Are you having issues with BPT's running in an infinite loop? Going crazy trying to figure the issue out? Well looks like this is actually a known problem.
HP has just released a critical patch for people using QuickTest Professional 11 and ALM/QC 11.00 with BPT. The patch resolves an issue with settings that were setup for normal QTP test were sometimes incorrectly applied to a Business Process Test run. These setting caused the BPT to run in an infinite loop.
Patch QTP_00821 can be downloaded from HP.
