Yes, 3.3.2 flashes up ‘trial mode’ as well as 3.3.3, whether offline or online. But if offline, it flashes so fast that you have to be eagle-eyed to spot it. If online, it’s for a second or two.
It may be for security reasons of course but I’d have thought the same thing could be accomplished ‘silently’ so we’d never see it unless unlicensed. Either way, it’s a minor ‘bug’ and there are much bigger fish for Topaz to fry.
