What Build No of Delphi do you use, for example Delphi XE2 Update 3(16.0.4358.45540)?

Have you already installed any 3rd-party plugin?

Aysen Deger at 2/3/2012 6:43:23 AM -
No I haven't installed anyplug in to Delphi. But I have lots party of 3-rd Componenets. I've attached a sample project.

What OS do you use, for example Windows 7 64bit?
and, what system locale do you use?

Aysen Deger at 2/4/2012 3:26:45 PM -
Windows vista 32bit home premium Service pack 2
and Turkish

Tomohiro Takahashi at 2/5/2012 7:22:44 PM -
ok,
Does your issue occur only with TLabel?
What about other components(e.g., TEdit, etc...)?

Aysen Deger at 2/6/2012 7:18:01 AM -
There isn't any problem at Tedit etc. Also  captions of Tpanels or  tradiogroups  etc works true.

but I have 3rd part comp  Rxlabel (I think it is driven from tlabel ). It has same problem.
I notice that when I open "String List editor" of TLabel.caption, Line number is 1 insted of 0.

Salvador Jover at 4/25/2012 4:15:10 PM -
Hey Aysen, please, you can unnistall RX and you will see its works fine.

You can see RxHintProp.pas. GetEditLimit function always return 2 with XE2.

RX overrides the property editor for Caption in TLabel class. (RxCtlReg.pas)

Line 528  RegisterPropertyEditor(TypeInfo(TCaption), TLabel, 'Caption', THintProperty);

You can comment this line.

Today we have commented it in Delphi Solidario Facebook for Spanish people.

Salvador-san
Thanks for the information. I updated internal status of this report.

Please use Windows Native QC Client to attach a .zip file to your existing report.
The standalone client comes with Delphi.

sorry I wrote wrong update number.

I have  Delphi XE2 Update 3 and Embarcadero RAD Studio XE2 Version 16.0.4358.45540

Tomohiro Takahashi at 2/2/2012 5:46:44 PM -
Ok, I corrected fields of this report as Sysop.

Sascha Willems at 5/4/2012 1:08:09 AM -
We're encountering the same problem here at work.

OS          : Windows 7 64-Bit
Target      : Windows 32 Bit
Delphi XE 2 : 16.0.4429.46931 (Update 4)
Locale      : German

It also affects TLabel.Caption editor window, but even worse, sometimes you can't type any letters at all.

Tested with several projects, even a new VCL project.

For testing I disabled all keyboard-related plugins, but no change.

Sascha Willems at 5/4/2012 1:31:47 AM -
Note : I did comment out the line 528 in RxCtlReg, recompiled the rx Packages and installed them again, now it works as expected again.
