Double click to execute the onpress function

Hi, all
I wrote several functions within a GUI, the onpress() function worked fairly well with first button, but as for the second button, it works only if I click it twice.
I encountered this problem once with a very simple model and a GUI, the solution I chose then is to open a new model and created the same GUI for a next time. However, perhaps there is something easier to do with this problem.

I share your confusion. This shouldn't happen. Try putting pt("onpress called");pr(); at the beginning of your onpress code and checking the output console. Maybe the code is being called, but the nature of your code switches something each time.

Thanks, Alex!
Clearly and instantly I find a "onpress called" at the ouput console, however, the result of my onpress fuction appears several seconds later. Perhaps it is because those for loop codings within the onpress function, which controls output of two globaltable.
In addition, my ortho window turns out totally black before compiling the model, is that normal or because of some codings I added?
Eager to know the answer~~

I'm not sure about the compiling, but I think I can help with the tables. Your code probably looks something like this:

for(int row=1;row<=gettablerows("mytablename");row++){
    for(int col=1;col<=gettablecols("mytablename");col++){
        //you probably don't do something this simple,
        //but it's just an example that doubles each value
        double value=gettablenum("mytablename",row,col);
        double newvalue=2*value;
        settablenum("mytablename",row,col,newvalue);
    }
}

This is slow because every time it references the table, the Flexscript interpreter must parse the string, search through all the tables to find one with the same name, then find the row and column, then do something there. To optimize this code a lot, do something like this:

treenode tablepointer=reftable("mytablename");
for(int row=1;row<=gettablerows(tablepointer);row++){
    for(int col=1;col<=gettablecols(tablepointer);col++){
        //you probably don't do something this simple,
        //but it's just an example that doubles each value
        double value=gettablenum(tablepointer,row,col);
        double newvalue=2*value;
        settablenum(tablepointer,row,col,newvalue);
    }
}

This only parses the string and searches once. Each time it needs to find the table, it already knows where it is.

Thanks a lot, Alex!
Love the idea!
