I'm sorry for your difficulties.
You may not be aware, but there is a major update to HealthFrame (v3) just around the corner. Sadly - it does NOT have the feature you are looking for (making it easy to delete lots of tests all at once). We are reluctant to make it too easy to do something you cannot undo, but might want to...
However, the way we manage tests internally has been completely revamped. I hope any performance issues you are seeing we either have, or can, correct.
If not for the speed issue - I gather you would be OK with (and even prefer) keeping your old data - right?
Please send email to support@RecordsForLiving.com - and ask to enroll in their beta program. We will then send you information on how to download and test that the performance problem has been corrected (or we will work with you to get it corrected).
Can you tell me the number of tests you have in your PHR? We can at least create a sample PHR with that number of tests to verify on our own that this isn't a problem....
