Another "Cubase steals my keypresses" thread

I searched around the forum but couldnt find any info on this, im sorry if this is a duplicate / already known bug.

Bug: Some keypresses that are used by cubase as shortcuts are not sent through to the plugin, specifically those based on “alt” key. Pressing for example “alt + p” generates a keyPress inside JUCE whereas “alt + o” does not.
Simply pressing “alt” key alone does not generate anything either whereas “ctrl” does.

OS: Windows (10)
Host: Cubase 8 and 8.5 64-bit has the same issue, cubase 6 64-bit works.

Is there a workaround or are we screwed?

In general, you want to avoid using shortcuts which are also used by the host.
