Serious bug: Some keys are unusable in "A key was pressed"

I’ve found serious bug in the editor. When using A key was pressed condition, we can’t select numbers. We can use numpad numbers, but not regular ones. Entering number directly into key box instead of using press a key GUI also does nothing good.

Yes, it’s a known bug of the linux version.
The same bug make impossible to provide a version of Widgets Extension (one of my extensions) for GD Linux…

See 4ian’s post here for a solution.
