X-1.0rc3: IDE: "with Region" doesn't work after first run - uses whole screen --- workaround

--- workaround

put the code block (no indentation !) between

setROI(some_region)
#...
# code
#...
setROI(SCREEN)

----------------------------------------------------

# According to http://sikuli.org/docx/region.html#grouping-method-calls-with-region
# "All methods inside the with block that have the region omitted are redirected to the region object specified at the with statement."
# Based on this statement, I would expect the following code to only highlight the bottom three icons.
# Tested on both 64 bit Windows 7 and OSX Lion with identical results.

# Version: Sikuli X 1.0rc2 "Maltese" Released on 2011/02/10

# Expected results:
# * The script should highlight the test image, the bottom half of the test image, and the bottom three icons in the test image.

# Actual results:
# * All 6 icons are highlighted.

# Steps to reproduce:
# 1. Close all running copies of the Sikuli IDE.
# 2. Open TestImage.png in an image viewer at 1:1 zoom level. (Possibly by viewing the .html file)
# 3. Open the Sikuli IDE and load this script.
# 4. Run the script. During the first run you will see the expected behavior. It will only highlight the bottom three icons.
# 5. Run the script again. This time and any time after, it will highlight all 6 icons. This is not the expected behavior.

testimage = find()
testimage.highlight(1)

bottomhalf = Region(testimage)
bottomhalf.setY(bottomhalf.getCenter().y)
bottomhalf.setH(bottomhalf.getH()/2)
bottomhalf.highlight(1)

with bottomhalf:
        icons = findAll()
        sorted_icons = sorted(icons, key=lambda m:m.y)
        for icon in sorted_icons:
                icon.highlight(1)
