Problems about Toolbar (or container) loading

I’m am trying to load my plugin, it was compiled for Rhino 7, (Tdyn Wind Tunnel) to Rhino 8 Beta.

When I load my plugin, the toolbar (container) is not loaded automatically.
However, I can load my plugin (manually) using menu options and sometimes, not always the toolbar is loaded.

When toolbar is loaded, it is not possible to see the icon but the text is visible.

Moreover, the following error message appears:

First of all, I would like to ask if it is possible to load automatically any plugin when Rhino is started.
Can I do something in the code of my plugin to do this?

Secondly, I would like to know if I must compile my plugin for Rhino 8.

Third, I had problems like these with Rhino 7 but it was solved in recently versions of Rhino 7.

Thanks

Hi @Jaume_Sagues,

Where can we find your plug-in?

No.
