I commented this in another thread, but it doesn't hurt to repeat it.

When you find a problem with RAD Studio, make sure to create a report in https://quality.embarcadero.com  
And - please describe the problem properly!    What you are trying to do The actual result you got The result you expected Most important: How to reproduce the problem
- either as a detailed step by step description
- or as a small, self-contained, compilable example project
- or both of the above   Better reports = better chance of getting stuff fixed.
