ToneLIb GFX Online on Linux

Hi Team.

I use Tonelib GFX, v. 4.8-5, on Ubuntu Studio 25.04
I was resigned to the idea of not being able to check the online presets with ToneLib GFX, until now.

Using Reaper as a DAW, set the VST3 plugin for an audio track by using ToneLib GFX.
From the plugin, I can login and try some online presets!!! (see attached file)

It seems that using only the application alone of ToneLib GFX is impossible to select/type username and password.

It seems a bug... could you check it?
thanks
