Hello
Some week ago I switched 14.2.1 from 14.0.58. Lately I realized that all forms using TIWTabControl doesn't work anymore throwing an Access Violation error clicking on tabs bar (Please see below the trace-back)
I checked my project and even in the IDE (RAD studio XE) the issue occurs.
Testing is quite simple. Just place on a IWForm a TIWTabControl, add few pages and then click on the tabs bar and observe the pop up dialog reporting the AV error.
Has anybody else experienced/reported this issue?
Has been fixed in earlier releases? (unfortunately I cannot further upgrade since 14..2.1 is the latest version allowed by my license)
Does a workaround is available?
Thanks in advance
Andrea
