OK, with wx 2.6 I can reproduce the problem.

Can you try r2161? For me this delays the problem until you open
multiple igrid browser and close one of them.

One solution might be to only allow one igrid browser. The other would
probably be that all igrid browsers are frames in only one wx application.
