Microstation V7 had a toggle button that prevented "text" items from taking on a linestyle other than solid. It was located under workspace-preferences-text. Where is this option for V8i?
This switch is no longer available or valid since all text will display solid. If you are seeing text with different symbology, it has a Broken Association or Has been dropped to line work. Check the User Preferences under Operation > Display Broken Associations with Different Symbology. Same setting can be found in Plotting dialog under the Print Attributes.
