Comment 24 for bug 1767848

@orsommmz : Sorry, your change had no effect.

The hang appears to have something to do with the dimensions of the symbol preview window in the Choose Symbol dialog. If I resize the dialog so there is more room in the symbol preview window and then click on the Flir_LEPTON symbol in the list, there is no hang. If I close KiCad and restart it, so the dialog returns to its default size, the hang occurs when I click on that symbol.
