Two workbooks + two macros = Crash !

Two workbooks + two macros = Crash !

(OP)
I am writing a series of spreadsheets for tubular joint design and am really stuck with a macro problem. I've only recently started learning VB and any helpful advice would be most welcome.

I have written a Master Excel workbook which contains common values and information to all the joints. Each specific joint has its own workbook. The Master workbook contains most of the code which is common to the other workbooks. The idea being the user always has the Master workbook open and at least one specific joint workbook. So far this has worked well.

I have written a macro in the master workbook which saves the specific joint workbook input values into a text file. No problem here.

Another macro, again in the Master workbook, extracts the values from the text file, opens the correct specific joint workbook and enters the values in the correct cells (using names cells. This basically works fine.

My problem is the specific joint workbooks contain tickboxes and option boxes which has click event code in the workbook to changes values, hide/unhide lines and blocks of lines. Each of these tick/option boxes has a linked cell (TRUE/FALSE depending if its ticked). When the Master workbook macro, extracting the text file values, puts the TRUE/FALSE value in the tick/option box linked cell Excel crashes. I think it may be because changing the tickbox sets off the click event macro written in the joint specific workbook while the Master workbook's macro is still running. I have tried turing screen update and autocalc off with any luck - it does not affect the macros anyway. I have tried assigning a variable when the text file values are being entered into the joint specific workbooks, with the click/option boxes click event macros first checking this variable value and aborting if true, but still it crashes.

Anyone any ideas?

Is there a way of stopping the specific joint workbook macros running until after all the values have been entered?
