I'm running wxFormBuilder Version 3.4.2 (Unicode)

If you create a form, Add a sizer and change the sizer Label to nothing or blank. Then add a notebook item, add a panel,add a sizer to panel and change it's label to nothing or blank. Click off the object properties and it will crash with:

New Note it appears if you change the label value of a sizer object then add an object to the sizer change it's label and click back in the designer window on your gui it crashes

Confirmed.

I notice very simlar crash after clearing labels from two wxStaticText.

[Bill Miller]

I can consistently reproduce this crash (same stack trace) just by leaving ANY text control modified in the properties grid THEN clicking on any control in the Designer pane.
(typically something like a listbox, button or calendar control)

So, change the name of one control in the Properties grid but don't click off or hit enter.
Then click on a button control in the Designer pane and bam.
The trick is a text control in the properties grid must be modified.

To get around the crash just hit enter first on a modified property text control.

I have the same problem.

I am running wxFormbuilder on Windows 10 64-bit. I get these fatal errors also, all the time. I am running version 3.5.1-RC1 (Unicode).
