VBA code stopping when secondary workbook manually closed (waiting for user to close second workbook) - excel

Question

I'm looking to have primary workbook (WorkbookA), open a second workbook (WorkbookB) and test for a value within it. Value to match is in WorkbookA, cell B3 and is the number 1. Range to test in WorkbookB is "A:A".
If the value is not found, WorkbookB is reopened for the user to edit (will optimize to reduce opening/closing, any ideas on getting user input to resume would be appreciated after editing Workbook B), and the code in WorkbookA loops and retests if WorkbookB is still open every 10 seconds.
After the user edits WorkbookB to ensure the value is present, they close it (any better way to signal they are complete is welcomed so I don';t have to close and reopen the files. They are small, so it's not an issue for speed, just seems inefficient).
The assumption I had was that the code would then detect the workbook was closed and then continue code execution, but the VBA is stopping as soon as I select the X in the top right corner of Workbook B.
Would prefer not having separate code in personal.xls file because of multiple users.
Thanks,
Aaron
Code in Workbook A:

Do While IsWorkBookOpen(strWBb) = True
endTime = DateAdd("s", 10, Now())
Do While Now() < endTime
DoEvents
Loop
