With last update got some lags in tabs migration
When migration from tab to any other tab (not clear) i see picture from 1st tab(3-6 sec), after 3-6 sec normal picture. (Sorry for bad English :( ) Mb do some screen-shots, if can but it is hard.
Please make sure that all of your plugins are up to date and that there is not more than one version of the same player installed:
Also which version of 37 is being used? beta or release?
