Hi,
lfm streaming failed with TLabel in TTabsheet as the
first control or the ONLY control.
Not sure if its just me, or anyone else experience this,
but here goes...
Using 0.9.17 rev. 9631
gtk1 on Gentoo Linux
Steps to produce error:
1. Create new project.
2. Place a TPageControl on the form and add a new page.
3. Place a TLabel in the newly created page.
4. Save the project.
5. Reopen the project.
6. Press F12 to view form.
At step 6, the form designer will not show the form.
Instead the IDE opens the lfm file in the source editor.
Below is what the commandline shows when F12 is pressed:

===========================================================================
Note: TNotebook's TPage also presents the same senario.
Also 0.9.16 stable release does not have such problem,
form is displayed successfully.
Other controls does not present this senario,
so I'm guessing TLabel has problem streaming when
contained in TPage.

Funky Beast
