Is there a response to the question posed 2 months ago by Gary Hazard?
You have a very nice program which I am using for determining the natural frequency of flat plates. Questions 1  4 have been answered by John Doyle, however I'm curious about responses to questions 5, 6 and 7 below and would appreciate guidance from you on these points.
5. What is the meaning of a1, a2, b1, b2, c and d? Do a1, a2, b1 and b2 signify the dimensions of a generalized polygon with different dimensions a1, a2, b1 and b2?
>>> I am also unclear on this please raise a comment with the author on the download page.
6. What is the meaning of “c” and “d”? They appear to the be midpoints in both dimensions of the plate, but I’d like to verify this interpretation.
>>> I am also unclear on this please raise a comment with the author on the download page.
7. If a1, a2, b1 and b2 are dimensions of a polygon having different dimensions for all 4 sides, then how are these 4 values inputted into the Plate Frequency Calculator in cells B5:6?
>>> I am also unclear on this please raise a comment with the author on the download page.
Thank you in advance,

I tried saving the workbook when set to Automatic, as Excel should remember the last state.
Nothing helped until I disabled XLC addin. After that Excel started behaving normally.
Toggling XLC addins "Auto XLC" does not have any effect.
Any suggestions?
Does XLC addin run any macro on startup?
Does XLC addin change excel template workbook?
XLC 15.03.16 on Excel 2007 @Win 7 64bit.
Close Excel.Uninstall XLC.Download and install the latest version of XLC.Restart the computer.
I hope this settles things down but by all means contact me again if you continue to have problems.Download XLC.Extract the zip into a folder on your hard drive.Right click on the file
The intention is to make sure that trial users are use the latest version of the software (active XLC Pro subscribers should never see this message).
You can close the message by clicking the top right hand "X" button this will take your browser to www.ExcelCalcs.com but Excel should remain running. Switch back to excel and press the about XLC and settings button . This will raise a form and at the top of the form it will state the expiry date for trial users. The latest version is set to expire on 29th February 2012.
Can you tell me what your system says to you?
I have not got to the bottom of this yet but I have disabled the skype addin and all seems to be working fine again.
I think you have merged the cells. To unmerge select the merged cells. Then a right chick with the mouse button should show "Format Cells"  select the "Alignment" tab and under "Wrap text" and "Shrink to fit" you'll see "Merge cells"  just uncheck this box and all should be good again.
I hope this answers all your questions.:)
1) Start Excel. Go to Tools>AddIns... This displays the Addins form and check that xlc is shown as installed. If OK then proceed.
2)Is the XLC toolbar visible? Check Excel MainMenu>View>Toolbars> and XLC Tools should show with a check mark next to it. If OK then proceed.
2) Check that XLC function are working. Type "=OVD(3)/und(6)" into a cell. If the cell returns 0.5 then XLC functions are working OK. If OK the proceed  if not install XLC.xll manually by following these instructions. From the addins form select the browse button and navigate to your XLC installation directory (normally this is C:Program Files>XLC unless you installed it elsewhere). Select the xlc.xll and press 'OK'. This has manually installed xlc.xll
Let me know how you get on.
