Summary0012600: input once, display twice
Descriptionmy os is Linux 0000001 SMP 2008-10-21 16:30:26 +0200 x86_64 x86_64 x86_64 GNU/Linux (OpenSuse)

the control which inherited from TWinControl, such as TEdit, TMemo, TSynEdit, has the same problem that when enter any key into the control, it would be display twice.

the other program on my system has ran good, I don't know what the problem is.

is this the problem about lazarus or about gtk2 configuration in my system

by the way, when choose gtk, it would be ran good.

Please, add an example application?

Are keys duplicated in the Lazarus source editor too?

It happend when I open the Lazarus, and put any TEdit or TMemo control on the form.

The Lazarus source editor has no problem, but it could not accept the Chinese word input, so I doubt the problem is relation to my Linux configuration.

Does it happen with Latin chars and/or Chinese chars?

I found that, when I attached the TEdit's event OnKeyDown, and assign the 0 to Key. The key I pressed will be display in the EditBox once.

On the forum it is suggested that this is related to SCIM (The Smart Common Input Method platform), once disabled the problem should disappear?

No feedback from reproter.
So I assume it indeed is a duplicate of 0015185, hence resolving this one.
