I have never used hyperlinks before, so I may have missed some critical steps
I have a lot of shortcuts to web sites and wanted to use hyperlinks instead - in calc.
I replaced the first 7 okay as follows:
Insert Hyperlink
http://www.iufcu.org
form button
text IUFCU
works fine
after adding 8th http://www.tdameritrade.com
form button
text TDAmeritrade
it works perfectly
BUT
All the menus, even top right red X appear, but are BLANK
