The issue is most likely caused by poling the state of the key 96000 times a second and only acting upon it in modem poll 10 times per second. The solution in the 64-bit branch was to adjust modem_poll to check multiple times in each call.? The transition states are being made but not acted upon.
/*
This file implements modems for :
Fldigi: We use fldigi as a proxy for all the modems that it implements
?
?
General:
?
There are three functions called to implement almost all the digital modes
1. There is the modem_init() that is used to initialize all the different modems.
2. The modem_poll() is called about 10 times a second to check if any transmit/receiver
changeover is needed, etc.
3. On receive, each time a block of samples is received, modem_rx() is called and?
it despatches the block of samples to the currently selected modem.?
The demodulators call write_console() to call the routines to display the decoded text.
4. During transmit, modem_next_sample() is repeatedly called by the sdr to accumulate
samples. In turn the sample generation routines call get_tx_data_byte() to read the next
text/ascii byte to encode.

I need to look at the details more to verify that the comment is accurate.
