Graphs legends are black when using subpanels

[pablomendana]

Hello.
I have a VI based in subpanels architecture. Different VIs are called and loaded in a subpanel depending on a user selection.
Most of this VIs contain some graphs and charts. Each graph has its own legend for X and Y axis. This legends change depending on magnitude shown.
When I run each VI indepently, legends are shown with transparent background, so they are perfectly visible, but when I run the general application, all the graph legends in every VI loaded in the subpanel has black background and legend is unreadable (only a black rectangle is visible).
What can I do to avoid this problem? I think that maybe there are some control properties that have to be modified. Is it correct?
Thanks!

I had this problem at one point.  I simply changed the color of the area behind the text in the scale label to match the graph background so it isn't transparent.  It's quick and dirty, but it works, and I couldn't figure out why a black rectangle was being shown only when a graph was loaded as a sub VI.

Hope that helps
