Glenn Zieman writes that when using BBEdit (running Mac OS 7.6 on a 6300), the HTML palette shows up without the buttons (a blank window). The individual buttons will show up one at a time if you click in the window or all at once if you clink in the name bar. He contacted Bare Bones about this and they replied:
"If you hold down the Delete (backspace) key while BBEdit is starting up, the palette will throw away its existing settings and revert to factory defaults. This should also cause it to reposition its window to a factory-default computed location."
