Chapter 8. Frequently Asked Questions

1. Menus seem broken under KDE.
   Under KDE 1.0 (1.1 is untested) you may need to click a menubutton twice to get the menu to post. This showed up when we moved from Tcl/Tk 8.0.2 to Tcl/Tk 8.0.4. To work around this bug, select one of the following focus policies in the KDE window configuration dialog: "Classic focus follows mouse" or "Classic sloppy focus". Note: this should be fixed now that we've switched to Tk's native menu code (for Windows compatibility).
2. File selection dialogs produce strange (Tcl/Tk) errors. Some versions of Tcl/Tk prior to 8.0.4 seem to have a bug in the Tcl/Tk file dialog code. If you see an error message like "Error: can't set "data(selectPath)": bad window path name ...," upgrading to a newer version of Tcl/Tk should fix the problem.
3. Changing waiter-prompt-and-read produced unexpected behavior. Changing waiter-prompt-and-read may interfere with the REPL's paren bouncing and indentation mechanisms.
4. Engines do not seem to work under SWL. The SWL thread system uses Chez Scheme's timer-interrupt mechanism, and so do Chez Scheme's engines, so the two are incompatible.
