grid problem with uicontrol

Hi !! I'm working on GUI figures and in one of them there's a plot. When I open another figure in my GUI (with a pushbutton for example) the plot in the first figure is covered by a grid and i can't figure out why this grid appears. I may not be clear but if anyone has an idea...or understand what I'm talking about.

My guess is that the code to create the second figure uses

grid on

without being careful about what the current axes is.

A lot of code relies upon a sequence such as

figure
plot(....)
grid on

which rely upon the "active figure" and the "active axes" be what the programmer expects. Unfortunately there are circumstances under which the active instance might have changed unexpectedly. It is safer to write code that always explicitly gives the handles that are being acted against:

f = figure;
ax = axes('Parent', f);
plot(ax, ....);
grid(ax,'on')

that's a common error for most new users of matlab :)
