Hydra 5 and Keyboard events

Hi

We have a project using Delphi XE 2 (Host) , Wpf plugins (.Net 4.5) and Hydra 4 for Years with no problem. After upgrade to Hydra 5 (we tried the last 2 or 3 subversions) all WPF plugins stopped to respond to keyboard (ordinary key, tabs, ctrl-c, etc).
Mouse events are ok, paste is ok (using context menu).

For testing purposes we returned to Hydra 4 and everything works fine again.

Any clue where to start to investigate?

can you provide a bit more info about your Delphi host: this one is FMX or VCL based?

VCL on Delphi Xe2 32 bits. A very standard app.

I can’t reproduce any problems with XE2 VCL host and WPF plugins with Hydra5.
Can you create a simple testcase that reproduces this issue, pls?
You can attach it here or send directly to support@

tested with Hydra 5.0.89.1157
