Hi,
I just replaced AC 7.68 with the latest version 8.03 and I have found 2 issues so far.
1. Icon of button OK (green tick) (TsBitBtn, kind = bkOK or bkYes) is not visible (maybe it is not related to this kind of button only). When you hover mouse over button, icon appears – it is visible only when button is highlighted. It occurs very often, but not on all these buttons. (Beijing Ext skin, Win7)
2. Extended borders of Beijing Ext skin are still visible when window is minimized.
