Starting with version 1.38.2 "Execute in browser" check works only for "Show preview". If checked and "Execute" is attempted, a popup window opens as usual but no action happens. Running without Execute in browser check works, but it is much slower than in 1.37.2. Execute in browser is useful as it does not suffer from timeouts for big updates (limited by 50 pages at the time only).
