Plot window not updating

Hello, I am new to Octave and I am excited to find an open source application to fulfill my needs, but I have found the following issue that I need resolved (sorry if this is a repeat of someone else):

 

I  downloaded the following executable from the Windows installer to my Windows 7 laptop:

Octave-3.2.4_i686-pc-mingw32_gcc-4.4.0_setup.exe (this exe uses plot 1.0.7, but I added 1.0.8 to no effect)

 

After starting the program I entered the following:

Ø      x=[1:.05:10];

Ø      figure;           {I get the following warning}

warning: isstr is obsolete and will be removed from a future version of Octave

 

At this point, a figure window is opened and when I move the cursor over the window I get crosshairs and the window updates the coordinates.  Any axes or labeling commands work fine. I can move and resize the window.

 

Then I try plotting data:

Ø      plot(x);

 

At this point the data does not plot until I issue another command to the plot (add a second line, grid, etc.).  When I move my cursor over the window I get an hourglass cursor (like a function is still running).  I can’t resize or move the figure window.

 

Note:  When I turn on the new backend (“backend (‘fltk’)”) , this problem goes away and the plot window responds to each plot command as expected (except that these plots do not support text).

 

How can I resolve this issue?

 

Thanks!

Dave
