Hi all,

I've got a workbook (xlsb) with a couple of form controls, two images with attached macros and a combobox
the combobox regularly fails to operate, and throws a second image of itself a little distance away if it is clicked - and otherwise fails to do anything.
I've deleted and replaced it - and get exactly the same result.

I run Win10, office 365 (64 bit) and found this problem after migrating to a new laptop (prev lappy was running the same config), and getting windows and office updates - though am not sure if this is connected or not.

when I was adding the replacement cmb, I added the new one first, typed in the config, and had both cmb's working. I deleted the old one, added data to a table, and found the new cmb acting the same as the old one.

I had more issues that I fixed by adjusting trust centre settings, and now have macro and activeX security set to ask before running, and have the folders (in onedrive) set as a trusted location.

does anyone have ideas on where this is coming from or how to beat it?
thanks
Werafa

addendum:

hmm, that is annoying.
saved it as xlsm - it didn't work.
closed excel, and had some document recovery stuff appear
closed this and opened the xlsm, it didn't work.
closed this and opened the xlsb - it started working.

can't call this a solution though as it has 'started working' several times before
