"Drop shadow" in Frame 11 tab text

[Saunders, Ian]

Hi,

Apologies if this has already been covered, but I have only just upgraded to Frame 11, and am finding the text in the document tabs almost unreadable because of a white drop shadow. 

Has anyone else experienced this, and - if so - is there a way of adjusting the text to make it readable?

Windows 7
Frame 11.0.1.382, part of TCS4, all updates applied.

Many thanks.
