Multiple elements do not work

I am a new user looking to buy. I have downloaded and installed the trial to make sure the program will do what I need. After using it for a short period of time I have found issues.

My primary concern is with the following scenario: I loaded a large image of an object I want to prototype – for example an image of a remote control. I created two shapes for simple testing, let’s call them Element A and Element B. I added behavior event actions to Element A so that when it was clicked it toggles the visibility of Element B. I also make the opacity of Element A change when clicked (Mouse Down / Mouse Up) so the user had feedback that A was indeed clicked.

Here is the problem: When I use rectangles for the elements everything works perfectly. But if I use Ellipse, triangles, or polygons it does not work. Nothing at all happens when I click the elements unless they are rectangles. I have only tried using these 4 types so the problem could extend to other objects, but 75% of the 4 I tried do not work. I have switched back and forth between rectangles and other shapes and back to rectangles about 8 times to make sure I was following the exact same steps and setting the exact same settings and I can confirm I am. For whatever reason, my clicks only register for rectangles.

The first elements I tried were Rectangles and I was so pleased with how well this program worked, on multiple browsers, simple yet powerful, and I was excited at it’s potential. But now after branching out I am nervous that the next features I worked with are broken and wonder how many more bugs there may be.

My secondary complaint is that the application behaves differently between the different “look and feel” settings. Personally, I prefer the look and feel of my local OS. However, when set to “System Look and Feel” the program is more buggy and difficult to use. I was forced to change back to EaSynth for usability. For example, when I try to create a new rectangle by selecting the rectangle tool, and then clicking on my plot and dragging an appropriate sized rectangle into existence, the behavior is different for each setting. Under EaSynth the moment I click on my image a rectangle is created (larger than the one I was trying to create). The size of the rectangle does not follow my mouse pointer – I have to resize it by moving my mouse out to it’s current size before it then follows my mouse. This is not ideal, but it is functional. When System look and feel is selected, however, when I click on my plot and try to drag the rectangle size to my desired size the pointer drops the rectangle altogether (EVEN THOUGH I HAVE NOT RELEASED THE MOUSE BUTTON) and automatically grabs an underlying element. This is absolutely unusable because everytime I go to create a new rectangle I accidentally move random elements that were already perfectly placed.

EDIT: I forgot to mention that I am using 3.90 SP2 (the most recent version), on Windows 8.1 64-bit. I have tested in Firefox v39, IE v11.0.9600, Opera 30.0, Chrome 43.
