I have not seen that myself but I can pass along some ideas. In LV 7 there is now the option to designate on a VI by VI basis, the "release memory as soon as possible". If this is turned on for a VI that uses large amounts of memory and called repeatedly, this could cause issues.
Another more likely candidate was mentioned in the release notes. The "defer front panel updates" will now update the FP once when set true, and again when set false. This could lead to double the number of screen updates! Otherwise; The 100% symptom is generally a sysmptom with many possible causes. Try using the profiler to narrow down the possible culprits. Post code if you want some to look and advise. Trying to help, Ben
