did you re-run the plugin scan? in most of my projects, the v11 plugins came up correctly because they had the same name as the v10 and v9 plugins. re-running the scan should re-acquire the actual underlying plugins via the wave-shell dll (which has definitely changed).

it may be the zoom function operates too quickly and the number of events to process (rotating the dial or clicking on the +/-) overloads the software which is trying to process everything else. if i operate the controls slowly (+/-) it doesn't seem to happen. same with a single indent of the wheel. if i quickly spin it or click the scoll buttons it goes into the lock up and seems to be trying to scale beyond it's limits and/or has too many operations to attempt.
