#### Resulting executable will be

 Also, I wanted to change the cursor which was cross-hair initially to an arrow. 

This can be changed as shown. https://github.com/OpenBoard-org/OpenBoard/issues/91 Hi, There's no setting for this, no. However, if you want to build OpenBoard from the source, you can easily modify the code that specifies which cursors are used. It is in src/gui/UBResources.cpp, and the possible cursor shapes are listed in the Qt documentation here.
