Hi Manuel,
The fact that TestComplete records interactions with a control named TextBoxMaskBox is caused by DevExpress controls' internal implementation - this internal control is created for every control with masked input, as far as I know. However, I'm not sure I understand what problem you currently face. A recorded test should be played back successfully regardless of the way the controls are implemented. If the test cannot be played back successfully, please zip your entire project suite folder along with the log of the failed test execution and send me the archive. Make sure that messages in your log correspond to the latest version of your tests. You can do this via replying in the support case you created (M0111343) to make sure your message gets the appropriate priority.
