Designer Edtior "Cannot paste the clipboard contents"

Hello Vaadin,

what is going on with the designer?

A time a go in the editor the paste operation inserted text twice…

Now I get the message “Cannot paste the clipboard contents” when copying a short text from the same source and tried to insert it.

Using the designer makes the work not easier.

Why not making the tool mor stable?

Often it hangs in the desinger mode when pressing the source tab…

Developing with Vaadin could be easer if the tools are not falling apart…
I can accept tools that have not a large bunch of features, but the should work.

Please, please invest more in stablility.

This should be considered if Vaadin should become an important choice on the market.
