There is a known issue that causes some of the dialogue boxes within SignalPro to display improperly. The best setting for the Display Settings>Scale & Layout of a users machine is going to be 100%.
This may not always be what is recommended from the users machine, but 100% is the only Scale & Layout size that will properly display everything. For example this image shows a mesh dialogue box at 150%, where just below the modulation settings, you can see the dialogue is displaying wrong.
If this is a problem and the user is unable to read the text at 100% scale & layout, the user will have to submit a ticket for the specific dialogue box(s) that is causing the problem. Another workaround could be to adjust the scale & layout with SignalPro open. This will enlarge the size of everything but the dialogue boxes will still display normally. But it is important to note that when re-opening SignalPro, the user will need to adjust the scale back to 100% in order to have the dialogue boxes display correctly.
