Problem with Brush Matlab R2015a

Since upgrading to R2015a from R2014a. Two problems came up.

I. Changing the transparency of an area filled with the "area" function in the following way doesnt work anymore: x=0:pi/10:2*pi; y=x.^2; harea = area( x, y, 3); h=get(harea,'children'); set( h, 'FaceAlpha', 0.1) ...this code works in 2014a, in 2015a the transparency doesn't change

II. Retrieving data points from a plot with the brush doesn't work anymore. In R2014a the following code worked just fine, in R2015a it doesn't give back anything;

x = 1:.1:10; plot(x,x) brush on pause hBrushLine=findall(gca,'tag','Brushing'); brushedData=get(hBrushLine,{'Xdata','Ydata'}) for I=1:size(brushedData,1) brushedIdx = ~isnan(brushedData{I,1}); Selected_X_Values{I} = brushedData{I,1}(brushedIdx); end fitCorrectStart(1) = Selected_X_Values{1}(1); fitCorrectEnd(1) = Selected_X_Values{1}(end);

I identified two problems here: - Once in the brush mode on the plot no key press will make the pause function continue. - If the pause is limited to 3 seconds by writing pause(3), although data has been brushed during this time the brushedData variable is empty
