Hello everybody,

if the version CnWizards_1.0.0.652_Unstable.exe is installed, I have problems with the styles designer under RAD Studio XE4 Enterprise. In the attachments are some reports. I do the following steps :

1. Open a FireMonkey HD Application
2. Put a stylebook on the form and set the property Stylebook of the Form.
3. Load an existing Style-File. (ex. c:\Program Files (x86)\Embarcadero\RAD Studio\11.0\Redist\styles\Fmx\)
4. Look in the details of an existing Layout.
5. Click on the Button 'Clear All'
6. Load another Style-File
7. The error was appeared

Or the error was appeare after delete an style or a TLayout.

Thanks for your report. I'll check it.
