(possible) Problem with spread sheet

Hi everybody,

Before I start let me apologize for this email because I don't really know who is reading, maybe 
I'm sending to the wrong person/people. If so, I'd appreciate if you forward to the right 
department.

I'm a simple user who uses basically your word document and spread sheet, and I'm quite satisfied 
so far so first of all muy utmost encourage to keep up with your excellent development and 
maintenance of this fantastic LibreOffice package.

However, I'm experiencing update after update that when it comes to highlight the edges of any 
given cell of the spread sheet I have problems to sort it out correctly. Up to a point that more 
often than I'd like I must give up and leave it as it is.

I mean, for instance, that I make a pattern for "working hours template" but as I'm using that 
template I highlight here or there... sometimes after giving the instruction and saving it, it 
doesn't show. Or perhaps if I call for it to 3 edges it happens to just one. And to be honest I 
thought I caught why this happens (maybe it's due to unify some cells and the new shape has 
"residual orders" that avoid different orders of the same kind), but not so sure lately.

This matter is exclusively of edges, regardless of whether you (try to) make them thicker or desire 
to change colour, etc. Other than that, your spreadsheet works really fine.

I'm sorry if my English isn't good enough (I'm Spanish) or I haven't explained the matter 
correctly, I hope I did well enough.

Many thanks in advance,

Juan

economic resources.
