Unfortunately this may be a bug.
To get around it please check the following:
1. Open Mocha
2. In the file menu: Select View - And check if 'Parameter' is ticked
If it is ticked then we need to reset the layout to do this you need to delete the preference file - On the Mac
Or the registry setting on Windows
To delete the preference file, please do the following:
1. Open Finder
2. Navigate [User]- Library-Preferences
3. Delete com.imagineessytems.mocha.plist and
1. Open Regedit
2. Select HKCU/Software/Imagineer Systems Ltd
3. Delete Mocha 1
Note: With both of these you are dealing with system files. Please be careful or refer to you IT guys when carrying out these tasks.
Sorry about the inconvinece, we hope this issue will be resolved soon.
