technology fun - why oh why!

Technology continues to delight!  Creating excel files yesterday, lovely worksheets - saving not as straightforward as it once was, gave me loads of options for what I would prefer to save as, did what I always do, went for any old one, opened it today and discovered only one of worksheets remains.  Currently re-doing yesterdays work.  Good job I went for a run this morning and feel energised.  I wonder if I can catch up with myself before seeing lovely clients this arvo?
