Today I added a TMS group box containing a few TMS controls onto a page tab and suddenly the labels for the other TMS controls on the same page disappeared. If I click the mouse on the tab, the labels reappear but as soon as I release the mouse they disappear again.
I'm using Delphi XE and Windows 7. If I remove that control group from the page, the label behave normally again. Video linked here. Any ideas?
