Which one is the most stable?
Mainly using it for Web testing, and some reading/writing to Excel files.
My team has a lot of code in each project, so we often need to run smaller suites of test, then reboot UFT before running the next suite of tests. Otherwise UFT crashes after clicking the run button - this was NOT an issue in the "QTP" versions. 12.02 is the most recent version we've been consistently using.
