« Prev | Next » Design Browser and Structure Window Pane Disappeared Description My Design Browser and Structure Window pane disappeared. How can I get those back? Solution You may try two things to resolve this issue: Try moving your mouse to the left side as much as possible and see if the cursor changes into bi-directional arrow. If it does, drag the border to the right. The Design Browser was possibly collapsed to the left. In this case you may be able to drag it back. If the step above doesn’t help, please do the following: Close Active-HDL Execute program in Aldec install folder /BIN/prefman.exe Use "Set Defaults" to reset current user preferences Previous article Next article
