Disappearing Track Names ???

This happens in the mix window.
After switching to another session and then back , names of audio tracks ( actually all tracks , group/output , etc…) suddenly will not display.
Reload of Nuendo needed to resolve issue.

Anyone ??

Nuendo 6.07/W7 64bit

Yep, happens to me as well.
It helps to zoom in and out in the mix window for me. The track names return after that.
