We are moving from WinXP to Win7. TxSL 6.1 is not supported by Win7 so TxSL 7.1 is the only option. I can't determine the differences between these major releases, so I've loaded the eval TxSL 7.1 to do a smoke test. I've attempted to load some of my TxSL 6.1 testplans and they load without error. However, my testplans have VBA-based routines and in TxSL 7.1 I can't seem access any of the VBA code. Am I missing something? Can someone give me details on the significant differences between 6.1 and 7.1?
