Something's gotten weird. When I open Excel, it no longer uses Book.xlt from XLStart as the new workbook template. When I insert a new sheet, it does use Sheet.xlt (both are present in XLStart).
I closed and reopened Excel, same behavior. Rebooted, same. Detect and repair, same. Then I opened and resaved Book.xlt, exited and restarted Excel, and it worked fine -- for a day. Now back to the same. Both files still in XLStart.
Anyone got any kind of a clue?
Thanks in advance.
