Lose access to clipboard when computer is locked

I have a script I use to process model simulation data and then plot results to PowerPoint using activeX.

Recently, after switching from Windows 7 to 10, I have noticed that if I lock my computer, not hibernate or sleep, the script will continue to run and generate the PowerPoint file. The only problem is that the plots have not been populated however the correct number of slides and slide titles are present.

Here is how I am running activeX:

copyfile('TEMPLATE.pptx',Fname)
p = actxserver('Powerpoint.Application');
pp = p.Presentations.Open(Fname); % open file copied from template
slide_H = pp.PageSetup.SlideHeight; 
slide_W = pp.PageSetup.SlideWidth;
ps = pp.Slides;
pT = ps.Item(2); 
pTs = pT.Shapes;
pT.Duplicate;
slide = 3;
pc = ps.Item(slide);
set(pc.Shapes.Item(1).TextFrame.TextRange,'Text','SLIDE TITLE')
% following is loops for each plot to be made
plot()
hgexport(gcf,'-clipboard');
pic = invoke(pc.Shapes,'Paste')
set(pic,'Width',0.95*slide_W)
set(pic,'Left',(slide_W-get(pic,'Width'))/2)
%
invoke(pp,'Save')
p.Quit();
p.delete;

Hi Duncan,

I have exactly the same problem when the computer is locked with windows 10.

My code plots the results from simulation data and then exports the figure to Excel. But when the computer is locked, my code crashes because matlab has no access to the clipboard.

Please let me know if you found a solution.

Best,
